In this paper, we propose a low-cost Zigbee network based multi-application sensor, which is capable of door open/close and water leakage detection for smart homes. The proposed multi-application sensor consists of a MCU, a tamper switch for anti-theft, and a water-leak switch for detecting water leakage or a reed switch for opening/closing door. We design a unique firmware program executing on the...
Coexistence between ZigBee and WiFi technologies, which operate within the same frequency band, is increasing with the widespread use of the IoT (Internet of Things). ZigBee devices suffer significant decrease in the sink arrival rate of packets in the presence of WiFi interference. To overcome this problem, many channel control methods have been proposed. The existing methods switch only ZigBee channels...
In this research, a wireless touch screen switch panel has been developed. The device is connected to the light bulbs through ZigBee communication. The wireless touch screen switch panel can turn on/off or dim all the lights in the room. Besides, there are two user profiles available to control the lights directly based on the preferences (i.e. turn on/off, dim the lights) have been made and InstaOn/Off...
Several challenges exist in developing smart buildings such as the development of context aware algorithms and real-time control systems, the integration of numerous sensors to detect various parameters, integration changes in the existing electrical infrastructure, and high cost of deployment. Another major challenge is to optimize the energy usage in smart buildings without compromising the comfort...
The Demand for wireless lighting is expected to increase in the residential environment, as well as building, gym, factories in these days. A large number of wireless lighting is controlled by a controller in these environments. We proposed an advanced touch-link algorithm to reduce delay time that occurs when connecting a lot of wireless lightings. The ZigBee switch and 128 ZigBee lightings are implemented...
Planning and management of energy are among the most important topics nowadays due to the fact that the existing power plants and systems fail to satisfy the energy demand and keep up with the daily developing technologies. To maintain the energy need of the existing systems, researchers are aiming to improve usage and savings of available resources and systems. For example, power metering system...
In this paper a wireless home automation system is presented The proposed system allows controlling devices in a home environment by using a simple Bluetooth equipped mobile phone. The mobile phone communicates with a main Bluetooth/ZigBee module that communicates with the different ZigBee modules acting as the coordinator of the ZigBee network established between all nodes where electrical devices...
Voice communication is the main part of wireless communication. ZigBee is a new wireless network technology, which includes low-rate, low-cost, low-energy consumption, and short distance. Although it is not designed for voice communication, its 250kbps bandwidth is enough to support the voice communication. In this paper, we achieve wireless real-time voice communication based on AMBE-1000, CC2530,...
Smart wireless home security technique is one of the emerging technologies for intelligent building surveillance. Many wireless technologies like Bluetooth and Wi-Fi have been used in this regard. In this paper we have proposed a Smart and Contemporary Home security system using low cost, low power Zigbee (802.15.4) standard. The Zigbee uses multi-hop communication for data transfer. The architecture...

In this paper, we present a novel hardware prototype implementation of a wireless communication system capable of automatically selecting one of several available commercial standards in order to minimize energy utilization while simultaneously achieving reasonable data rate performance. Without loss in generality, two wireless standards were employed in the prototype implementation, namely: ZigBee...
Radio irregularity phenomenon is often considered as a shortcoming of wireless networks. In this paper we present the method of using radio irregularity as an efficient human presence detection sensor which increases user awareness in smart homes. The idea is based on monitoring the received signal strength indicator (RSSI) between stationary wireless (2.4 GHz — Zigbee) power outlets. When a human...
The solid supply with electrical power in Europe needs the development of smart grids [1], [2]. To solve the control problems of these grids, smart metering devices and energy information systems (SCADA) are needed on the carrier level [3]. Considering private households and small enterprises, it is therefore required to replace plain old energy meters by modern smart metering components. Smart meters...
Ubiquitous services are an inevitable trend of our future. Nowadays, there are many wireless technologies that can be used and provide services to mobile users. If we can integrate their respective advantages and design a system to create an ubiquitous multimedia environment, it will be very convenient for people. In this paper, we will use Zigbee (IEEE 802.15.4), NFC (Near-Field Communication), Bluetooth...
To access the batteries information in the process of charge and discharge in time, the article designed a monitoring system for the condition of storage batteries based on ZigBee. This approach used the chip of CC2430, which was integrated of AD converter, 8-bit strengthened MCU and wireless RF unit. The chip of CC2430 and the external circuits were made up the node of the star network. The temperature,...
In case of maritime distress incidents, identifying the location of a victim is the foremost action in search and rescue activities. The existing search and rescue activities have been executed in the possible location identified by mayday of a victim or report from a witness of incidents. However, there are technical difficulties in precisely placing the location of a victim when a quite amount of...
